Frequently Asked Questions
Frequently Asked Questions (FAQ) submitted by you, real visitors and customers over the last few years.
No, unfortunately the Z-text modem is no longer manufactured and we have not sourced a similar item. The alternative is a GSM modem of which you will find a selection at GSM modems
AKCP
AKCP temperature and humidity sensors have a quite high accuracy and are calibrated by the supplier of the sensor. In general they do not need much calibration. The user could carry out calibration to verify accuracy. If needed you can adjust using the "Reading Offset". There is also a calibration certificate available on request for the probes.
The AKCP probes all have an RJ45 connector and can be extended where they are required via your structured cabling up to a maximum distance of 100m. Or, you can simply use standard CAT5 cable and one or more inline couplers to add extra cable to the probe.
Yes, single and 3 phase is supported by the same device.
Is it possible to use the SensorProbe2 to shutdown a series of three servers in a small server room?
Not directly or easily. Neither of the SensorProbe series products support switching off servers directly. It could be possible to send an email to a server and then have a job on the server wait for alert emails and then trigger the shutdown script. The AKCP SecurityProbe8 would be the solution of choice for this function.
The SecurityProbe8 provides a more direct solution as it is has a feature enabling it to shut down one or more servers. There is also a notification wizard for configuring the alarms. In this case you would need a temperature probe, the alarm could then be configured to execute a series of shutdowns when the temperature goes above a given threshold.
Thank you for your questions.
- SMS is only supported by using a third party Email to SMS service.
- Our montors are IP based and can be contacted by typing the IP address into a browser and can be made visible over the Internet.
- The Room Alert supports Pan/Tilt/Zoom cameras such as the AX-212-PTZ-CAM
The dry contact inputs on the X20 and X60 units can be switched from opto-isolated mode to non-opto isolated mode, where the E-opto16 inputs are all shipped as opto isolated and cannot be configured as non-opto isolated. Because of this, the E-opto16 inputs do require an input voltage as the module will not supply this voltage. When configuring the E-opto16 in the web interface of the securityProbe 5E and the dry contact input is set to the “Normal State” when voltage is applied, then the status will go to a “Critical” condition if nothing is connected, or there is no input signal to the dry contact. (no voltage applied). If the dry contact input is set to the “Normal State” when no voltage is applied, then the status will go into the “Critical” state when something is connected, or a signal is applied (or voltage applied).
ALPHA MICRO
Yes you can. There are gender changers available from various manufacturers, alternatively there is also a DCE version of the Netport Ethernet to RS232 Adaptor, the LAN02
It depends on the connectors on the devices you have. Netport LAN01 is the DTE version, LAN02 is the DCE version. Both devices are functionally identical but the one is Male-Female (DCE) and the other Female-Male (DTE).
Yes. The Netport connects serial devices to ethernet networks, allowing you to send serial data across the network, using a technique known as serial tunnelling.
The netport can be used in two modes.
- Single Netport mode: the Netport is connected to the PLC. A virtual serial port is installed onto a PC. Software on the PC can then talk to the remote serial device over the network. Whilst theoretically the PLC and the PC can be any distance apart, in practice the distance may introduce some latency into the system. That may be a problem if timings in the communication between the software and PLC are important
- Two Netport mode: the second mode uses two Netports. One Netport is connected to the PLC and it then talks to the second Netport over the network. The second Netport can then be plugged into another device or PC using a serial cable.
Yes this should be possible, but you may need to use 2 Netport adaptors instead of one. The use of a single Netport requires the installation of a software based virtual serial port. The driver software supplied with the Netport that implements the virtual serial port will only work on Microsoft Windows. We would need to know a little more about what you are wanting to achieve before we can give you a definitive answer, please get in touch.
AVIOSYS
Yes, you just need a commando socket with a C13 (kettle type) power lead to plug into the Aviosys device and a commando socket at the other end of the power lead.
Yes. All of the Aviosys remote power switches support operation through a telephone line and modem.
No. The IP9100A requires Internet Explorer with ActiveX support in order to display video feeds. Microsoft discontinued support for the Internet Explorer on December 31, 2005 and removed the application from their Macintosh downloads site on January 31, 2006. Even if you could get hold of Internet Explorer it wouldn't help because, whilst Internet Explorer will run on the Mac, the Mac version doesn't support ActiveX. ActiveX was always a Microsoft Windows specific technology.
Can I set one outlet to OFF then 45 mins later to ON; and do that up to seven times in one/same day?
You can set the schedule for a once a day action and repeat that every day, Monday to Friday and separately Saturday and Sunday. You can also set a delay on an action, so that On or Off won't take effect until a time has elapsed. In addition you can also use Wake on LAN so that a particular MAC address can wake the device up. However it is not possible to time multiple ON/Off actions on the same day.
No. The IP9200A only supports browser access to the video feeds. The video feeds from the cameras can be displayed using the built in web server. When movement is detected images can either be emailed or transferred via FTP'ed to a seperate server.
AVTECH Software
Yes, send an email to request the MIB files.
Yes the AVTECH monitors are supplied with 12 months maintenance and support. This is renewable after that date for a small charge.
It is not possible to connect a GSM modem directly to the RoomAlert. However this is possible with the AKCP SecurityProbe 5E device. We recommend the Teltonika G10 modem or the Samba 75.
The PS1 Power Sensor is actually a power presence sensor rather than a sensor which measures voltage/power output. It is a switch sensor that is normally in a closed state and will change state and therefore alert or change status, to loss or disruption of power for instance. The AVTECH PS2 Power Sensor alternatively shows real-time monitoring of amps, voltage and watts which you will find here I will email you the application note for the PS2 Power Monitor shortly.
The air flow monitor is only designed to work with the AVTech Software environment monitor units, as such AVTech Software don't release the technical specifications for their probes.
BI Communications
No TDRs are able to measure below 10m. This is because of timing difficulties with very short lengths of cable. The way to measure short distance is to extend the cable using a measured 10m or other known length of cable and measure from there.
Yes. The Faultcaster can determine the distance to fault on COAX cable, and on other cable types as well, up to a distance of 2000m (around 6000ft).
I will ask the manufacturer for a replacement CD and we will send it to you.
Yes the Faultcaster can be used on any type of copper cable.
Cable Testing
Yes there are guidelines to how much voltage you can run over CAT5 cable, these guidelines are set out in the specifications in IEEE std. 802.3af-2003 which added clause 33 to the IEEE 802.3 standard. It allows the powering device to use a voltage between 36–57 V DC, though the nominal voltage is 48 V, over two of the four available pairs on a Cat. 3/Cat. 5e cable with a selectable current of 10–400 mA subject to a maximum load power of 15.40 W. If you would like further information, wikipedia is a good source here http://en.wikipedia.org/wiki/Power_over_Ethernet
The ideal tool for testing real world networks is the Test-Um Validator which can generate real network traffic and verify that the traffic is transmitted correctly over your network. Alternatively, BI Communications produce a range of high quality TDR products which are able to quickly find faults in network cables.
A cable length measurement capability does not necessarily imply an automatic distance to fault capability. Testers that are able to select which pins to measure could be used to measure distance to fault, at least distance to breaks, but they would be very slow to use as you'd need to test each pair in turn. For a CAT5 and above cable that would imply four measurements to cable. Not ideal. Fortunately there are testers that will do all of that automatically for you. BI Communications have a range of inexpensive Time Domain Reflectometer products that can measure distance to fault.
Yes. The Faultcaster can determine the distance to fault on COAX cable, and on other cable types as well, up to a distance of 2000m (around 6000ft).
Yes. We are happy to help. Do you know where and when you bought the unit? The Test-Um Validator is supplied with a one year warranty so your unit may well still under warranty.If the Validator is out of warranty, we can arrange for a repair.
I will ask the manufacturer for a replacement CD and we will send it to you.
The Psiber Pinger+ is manufactured in the USA.
Yes the Faultcaster can be used on any type of copper cable.
Cable Tracing
Tracing POE cabling does introduce a challenge, how do you make sure that the power flowing over your cabling does not interfere with the signal generated by the tone generator?
The Test-Um KP100 and KP105 both have a feature that enables you to mask out mains interference which would be very useful when tracing POE cabling.
There are two ways to achieve this. The first is to use the JDSU TP607 LanRoamerPro Kit. This will allow you to trace (and test) cables in batches of 8. You would need to disconnect 8 cables at a time from the network switch, place the numbered remotes on these cables and then detect and re-connect. Alternatively, if you do not wish to disconnect any cables from the switch you can use the JDSU NT700 LanScaper network tester to hubblink each cable to identify it.
Yes. The Faultcaster can determine the distance to fault on COAX cable, and on other cable types as well, up to a distance of 2000m (around 6000ft).
Yes the Tone and Trace kit will work on any kind of copper cable. Obviously the twin and earth cable should not be powered. Both KP101 and KP105 produce a signal that can be traced through plaster, the Toner supplied wit the KP105 is more powerful and will penetrate a greater depth of plaster.
Yes the Faultcaster can be used on any type of copper cable.
Environment Monitoring
Yes it can make a difference, the main units are engineered to be quite resilient to RF but the cables may not be. If there are any concerns, then heavy duty cabling should be used to shield from RF interference.
The HWgroup range will suite your requirements perfectly. The Poseiden range of environment monitors support an optional GSM modem and has no need for an email/SMS gateway. In addition, the products are inexpensive and can support up to 8 temperature probes (depending upon the model.)
The AKCP SecurityProbe8 is a full feature environment monitor that is also capable of sending SMS messages directly via a SMS modem like the Falcom Samba 55.
The Recommended Server Room Temperature article goes into detail about the right temperature to run your server room.
The Sensatronics EM1 is capable of monitoring dry contact inputs, unfortunately it cannot generate a dry contact output. The simplest and cheapest options are the AKCP SensorProbe range and the HWgroup Poseidon range.
Both ranges come in a range of sizes and prices. For advice as to precisely which product would suit your requirements best, please get in touch.
Please read the Calculating The Size of a Server Room Air Conditioner article.
Certainly. Any of the products in the Rack Environment Monitor section would satisfy your requirements. All rack mounted environment monitors support additional probes. So you can place the environment monitor into one of your racks and then locate external temperature probes into each of the other 5 racks. Products to look at include the Sensatronics Senturion or the AKCP SensorProbe8. Alternatively, if you'd prefer reduce the amount of wiring you need to do, you could go for a product like the AVTECH TemPageR and place one unit in each rack.
A number of products suit your requirements. The AKCP range includes the SensorProbe8 that can take up to 8 external probes including dry contact probes. Whilst a SensorProbe8 would suit your requirement, I would recommend that you use the SensorProbe8-X20 which can take up to 20 dry contact inputs and 8 additional probes. Just in case you want to measure the temperature as well as monitor your backup generator. It is also able to send SMTP alerts.
Sensatronics also have a device that will suit your requirements. The Sensatronics Senturion can accept up to 8 external probes including dry contact input. It is also able to send SMTP alerts.
All network devices, one way or another, have a stage during setup and configuration of handling the network configuration. You can't escape it. In order to be able to browse to the device you need to know what the address is for that device. The AKCP securityProbe has a very unusual system. It is set to use DHCP by default and, when you push a button on the back plate, will tell you what the device's IP address is. The Sensatronics Senturion also has a very easy setup too. Because the Senturion has a LCD screen on the front, when it starts up and acquires an IP address, it displays the address on the LCD so you can configure it purely with a web browser.
For devices that support DHCP by default the easiest way to configure your DHCP server to give out a known IP address to the device's MAC address. That way when the device starts up you know precisely where it will be on your network.
Yes, we supply a free Software Development Kit for the Sensatronics range of environmnet monitors including the Model F. The SDK contains a number of samples to help you get started. If you want support for writing your application we would need to charge on a per hour basis.
The number of sensors really depends upon what you are trying to achieve. The simplest measure would be to measure the inflow air temperature at the bottom of the rack and the outflow air temperature at the top of the rack. That would give you a good idea of how the servers are affecting the temperatures all of the way up the rack. At the other extreme are the ASHRAE Thermal Guidelines for Data Processing Environments Second Edition that recomends a very high level of sensor density. The high density approach would be advisable if you wish to identify hotspots within your rack, especially useful after equipment moves which may introduce air flows that cause hot spots.
Each Sensatronics EM1 has its own web page that displays the current reading on each of the attached probes. In order to record the readings historically and graph the results you need management software. You can use a wide variety of management software, including many open source options like Nagios and MRTG. I would recommend you use Intellipool Network Monitor due to the fact that it is very easy to use and configure. Each Sensatronics EM1 would have its own page where you would be able to view historical charts of the readings over time. INM also includes a powerful report generator too in case you need ot create reports for your boss.
Yes, OPENXTRA can supply installation, training and on-going support services for your environment monitoring needs.
The cost of a Temperature@lert in Rupees, at today's rate 72.61 to the UK pound, would be 6898.28. International Delivery would cost 4720. We use TNT for deliveries.
Yes. Though you will need to install an update to the software you received with the Temperature@lert USB product. As of March 2010 new Temperature@lert products will ship with the patch already built in. If you need the patch please get in touch.
The Temperature@lert software uses the SMTP standard for sending emails. You need to enter the details of your SMTP server into the Temperature@lert configuration, usually just the IP address/domain name. If your SMTP server requires authentication (and if it is outward facing on the Internet you really should) then you'll also need to enter your user name and password on the advanced configuration tab. If your existing email client is using SMTP to send emails like Thunderbird then replicate your existing details from your email client inside Temperature@lert. You can easily test whether your email alerts are working within Temperature@lert, you don't need to wait until a temperature emergency happens to see if things are configured correctly.
If you are using Outlook and Exchange then things might be slightly more complex. You may need to enable the SMTP module on your Exchange server. If you have a dedicated Exchange team they will be able to furnish you with all of the information you need and enable the appropriate modules for you.
A USB device would be unsuitable for temperatures as high as 260C. You would need something such as the Sensatronics U4 and a high temperature oven probe for this type of application.
If you require a handheld thermometer with a probe take a look at the ETI models such as the 2003, which has a range up to 1000C.
Thank you for your questions.

The dry contact inputs on the X20 and X60 units can be switched from opto-isolated mode to non-opto isolated mode, where the E-opto16 inputs are all shipped as opto isolated and cannot be configured as non-opto isolated. Because of this, the E-opto16 inputs do require an input voltage as the module will not supply this voltage. When configuring the E-opto16 in the web interface of the securityProbe 5E and the dry contact input is set to the “Normal State” when voltage is applied, then the status will go to a “Critical” condition if nothing is connected, or there is no input signal to the dry contact. (no voltage applied). If the dry contact input is set to the “Normal State” when no voltage is applied, then the status will go into the “Critical” state when something is connected, or a signal is applied (or voltage applied).
There is no maximum distance. The area measured is indicated by a ring of laser dots. The further you are away from the target the larger the ring. The size of the ring of dots is a function of the Optics ratio, which is different for each model. Raytemp38 has a ratio of 30:1, Raytemp8 and Raytemp3 a ratio of 11:1, TN2 a ratio of 6:1 and TN1 a ratio of 1:1. For greater distances you would use the higher ratio units. Raytemp38 is a larger industrial unit good for relatvely large distances, TN1 would be used close to a measured surface.
It would only be possible to extend the Senturion probes over structured cabling using RJ11 to RJ45 converter and then extending, however, Senturion cables are available in a variety of lengths up to 100m and custom lengths are also available. Otherwise, other makes of environment monitor that have sensors with RJ45 connectors such as the AKCP monitors do offer the possibility of extending the cables via structured cabling (up to 300m)
The model F is designed and manufactured by a US based company called Sensatronics Inc so they are indeed compatible with US equipment. You can contact them at sales@sensatronics.com
No. There is no Windows Sidebar Widget available for the Temperature@lert that I know of.

FALCOM
Yes the SAMBA requires a SIM card. You can use either a pay as you SIM or a contract SIM.
Calls are charged via your mobile phone provider at the normal SMS text rate. You can negotiate the rate when you buy the SIM card that goes into your SMS modem.
Yes the SAMBA will require a SIM card
Calls are charged via your usual mobile phone provider at their normal SMS text rate.
Yes. The AT command set is documented on the CD that is supplied with the SAMBA 55 and SAMBA 75.
You can find the drivers for both the SAMBA 55 and SAMBA 75 at http://www.falcom.de/support/drivers-firmware/

Intellipool
Intellipool Network Monitor minimum software requirements are Windows Server 2003 or Windows Server 2008 with the latest service pack.
Intellipool Network Monitor
You can set up SMS alerts in Intellipool Network Monitor in several ways:
- using an email to SMS gateway or service;
- using a GSM modem in conjunction with Intellipool network Monitor. This has the advantage of working when your email server is down or otherwise unavailable.
The easiest way to do this is to install it on a different machine. On any given machine the 30 day trial will time out and not allow you to run it again unless you have a valid licence.
Intellipool is licensed per monitored object. An object can be a server, router or other hardware that can be addressed by an IP number. Included in the purchase is one-year upgrade protection.
Follow these steps:
- Shutdown your current installation by stopping the Intellipool service
- Install the new version in the same directory
- Restart Intellipool Network monitor service
Follow these steps
- Shutdown the Intellipool service
- Copy your INM folder to the new machine
- On the new machine, run "inmservice.exe -i -l WIN_USERNAME -p PASSWORD" to install the service
- Start the service (net start "intellipool network monitor")
Notice: if you want to run the service under the localsystem account, omit the -l and -p parameters.
We recomend using the SNMP agent. By monitoring the incoming and outgoing octets of a network interface with the snmp agent you can establish the bandwidth usage. The agent can capture statistical data that can be used to build reports with.
Yes, use the text file agent to scan log files for strings.
No, Intellipool Network Monitor has an integrated web server that supports both normal HTTP and encrypted (SSL/TLS) HTTPS.
Intellipool Network Monitor stores the configuration in a proprietary high performance database. The database is encrypted with a strong encryption algorithm to prevent tampering and unauthorized use.
Yes, by using the LUA agent users can develop their own agents by writing LUA scripts.
JDSU Test and Measurement
Yes. We are happy to help. Do you know where and when you bought the unit? The Test-Um Validator is supplied with a one year warranty so your unit may well still under warranty.If the Validator is out of warranty, we can arrange for a repair.
Yes the Tone and Trace kit will work on any kind of copper cable. Obviously the twin and earth cable should not be powered. Both KP101 and KP105 produce a signal that can be traced through plaster, the Toner supplied wit the KP105 is more powerful and will penetrate a greater depth of plaster.
We are able to ship to the Middle East, including Saudi Arabia, without any difficulties. We have the JDSU ValidatorPRO-NT currently in stock and can ship immediately. If you need further assistance, please get in touch.

Ordering
Yes. We offer reseller pricing on environmental monitoring solutions and everything else with the exception of SMS modems.
Yes. Please contact us by phone, fax or by email, we can offer you a 10% Educational Discount which is applicable to all universities, schools and further/higher education colleges. Unfortunately, at this time, you can't use the educational discount when purchasing online.
OWL
The Zoom II series can give you results displayed on the screen on the tester only. If you need to generate reports for records, export or sharing you require either the Wavetester series which will store up to 200 datapoints or the Fiber OWL series of testers which will store up to 1000 datapoints. Data can then be stored on a PC for later use using the OWL Reporter software which is supplied with the tester.
The OWL Fibre Testers are supplied with a 2.5mm universal connector on the power source. To test on LC connectors, the easiest way is to opt for an OWL tester with SC connector and then purchase an SC Fibre Connector Launch Cable Adaptor Kit which adapts from SC to LC, ST and FC
Psiber
The Psiber Pinger+ is manufactured in the USA.
Sensatronics
This reading indicates that the temperature, humidity, or wetness probe for that position is not connected. One possible cause is if the line has been cut between the probe and the EM1. Check the line, and make sure you have a good connection to the unit.
Yes you can download them here.
Probes are available in standard lengths up to 90m. However, it is also possible to build custom length probes up to 300m.
The Sensatronics E4 unit itself does not measure temperature, you will need to add at least 1 temperature probe. The unit will take up to 4 temperature probes. The temperature probe is a thermistor device which connects back to the main unit via 2-wire cable.
We can provide UKAS certified calibration on the Sensatronics E4 base units and the probes for 3 point calibration on all parts plus certificates, the UKAS-E4CERT is the E4 calibration service and the UKAS-TCERT the probe calibration. You would need to return the base units and probes to ourselves and the turn around is about 1 week, so what you might like to do is to have one E4 calibrated at a time so that you're not completely without monitoring. Alternatively there are on-site services available from other companies
You require a copy on Intellipool Network Monitor to use to manage the Senturion, (rather than the built-in software) and the SAMBA 55 GSM modem. Alternatively, you can use an email to SMS gateway service to translate emails into SMS messages.
The Senturion is a complete unit and will allow you to monitor temperature, humidity and light, set up thresholds and send out email alerts without any additional software or probes. It will however take up to 8 additional probes and can also send SMS alerts using Intellipool (plus a GSM modem) or an email to SMS gateway service.
Yes, the EM1 boxes can be managed using any SNMP based network monitoring application, eg. SNMPc, Nagios, WhatsUp Gold, and managed from one location on your network. We recommend Intellipool Network Monitor for managing and setting up thresholds and alerts.
The best solution (and the cost) really depends on precisely what you are atttempting to achieve. The Sensatronics range includes two products capable of measuring temperature, relative humidity and door open/close: the Senturion and EM1.
The Senturion is a rack mounted solution with built in temperature, light and humidity probes. You can either mount the unit in each cabinet or place a Senturion into a single cabinet and then run a combined temperature/humidity and door closure probes into the two other cabinets. You would also need a single door closure probe for the cabinet in which the Senturion is located. The Senturion is able to send email alerts, has a visual and audible alert and is capable of creating a historical log.
The Sensatronics EM1 is a wall mounted device witha built-in web interface. In order to alert you and create a historical log you would need SNMP based management software such as SNMPc, Nagios etc. We recommend Intellipool network Monitor
Yes you can connect both stationary and pan&tilt IP cameras to the Senturion, we recommend the TrendNet cameras for use with Senturion
The Sensatronics E4 is a simple temperature only monitor. It has a built-in web server so that you can view temperatures remotely. In order to set up thresholds and alerts via email, the E4 integrates with any SNMP based network monitor (you may already have something or we recommend Intellipool). You will also require at least one temperature probe, and obviously a network to connect it to!
The Sensatronics EM1 is capable of monitoring dry contact inputs, unfortunately it cannot generate a dry contact output. The simplest and cheapest options are the AKCP SensorProbe range and the HWgroup Poseidon range.
Both ranges come in a range of sizes and prices. For advice as to precisely which product would suit your requirements best, please get in touch.
This reading indicates that there is a short in the probe line; that the two probe leads are touching each other. Check the line for damage.
General recommendations suggest that you should not go below 10°C (50°F) or above 28°C (82°F). Although this seems a wide range these are the extremes and it is far more common to keep the ambient temperature around 20-21°C (68-71°F). However, more exploration of this subject can be found here.
I am by no means an expert on this topic but much depends on the size of the computer room, the amount of equipment you have in there, and whether you have air conditioning. Obviously, in a confined space with no ventilation or cooling, the temperature of the computer room is likely to rise, and it's the temperature that is the crucial parameter, not ventilation per se; and just as humans function best in an environment kept at around 21 degrees C, so too devices. General recommendations suggest that you should not go below 10°C (50°F) or above 28°C (82°F). Although this seems a wide range these are the extremes and it is far more common to keep the ambient temperature around 20-21°C (68-71°F). Whether you can maintain temperature with the use of ventilation alone or whether you will need some form of cooling will depend upon your particular circumstances. You will find more information here Recommended Server Room Temperature
The Sensatronics equipment used to be called Temp Trax several years ago and many of our earlier customers still refer to the Sensatronics E4 as a Temptrax Model E. The product is the same, just the name has changed.
The Sensatronics E4 supports SNMP so you can use many different network management tools to create reports, even open source tools like Nagios and MRTG are supported. The easiest way to create reports is using Intellipool Network Monitor. You can add a number of Sensatronics E4 or many other environment monitors to be polled by Intellipool. Intellipool has a very powerful report generation facility.
The Sensatronics E4 does support SNMP v1 and so can be used with a wide variety of SNMP servers like Nagios, MRTG and a host of others. I suspect that, from a setup perspective, it is much easier using Intellipool because a number of Sensatronics (and other environment monitors) plugins are available.
Yes, with the addition of a Wetness Probe you can detect water on the floor over a wide area. The wetness probe has a long conductive rope capable of detecting water over a wide area. The probe is particularly useful for detecting water in underfloor areas such as a server room or data centre raised floor areas.
The Sensatronics EM1 supports up to 4 wetness probes. Each wetness probe can be expanded to a further 7.5 or 15m with the addition of a Wetness Probe Extension.
Yes, we supply a free Software Development Kit for the Sensatronics range of environmnet monitors including the Model F. The SDK contains a number of samples to help you get started. If you want support for writing your application we would need to charge on a per hour basis.
Each Sensatronics EM1 has its own web page that displays the current reading on each of the attached probes. In order to record the readings historically and graph the results you need management software. You can use a wide variety of management software, including many open source options like Nagios and MRTG. I would recommend you use Intellipool Network Monitor due to the fact that it is very easy to use and configure. Each Sensatronics EM1 would have its own page where you would be able to view historical charts of the readings over time. INM also includes a powerful report generator too in case you need ot create reports for your boss.
A USB device would be unsuitable for temperatures as high as 260C. You would need something such as the Sensatronics U4 and a high temperature oven probe for this type of application.
If you require a handheld thermometer with a probe take a look at the ETI models such as the 2003, which has a range up to 1000C.
It would only be possible to extend the Senturion probes over structured cabling using RJ11 to RJ45 converter and then extending, however, Senturion cables are available in a variety of lengths up to 100m and custom lengths are also available. Otherwise, other makes of environment monitor that have sensors with RJ45 connectors such as the AKCP monitors do offer the possibility of extending the cables via structured cabling (up to 300m)
The model F is designed and manufactured by a US based company called Sensatronics Inc so they are indeed compatible with US equipment. You can contact them at sales@sensatronics.com
Serial Tunnelling
It depends on the connectors on the devices you have. Netport LAN01 is the DTE version, LAN02 is the DCE version. Both devices are functionally identical but the one is Male-Female (DCE) and the other Female-Male (DTE).
Yes. The Netport connects serial devices to ethernet networks, allowing you to send serial data across the network, using a technique known as serial tunnelling.
The netport can be used in two modes.
- Single Netport mode: the Netport is connected to the PLC. A virtual serial port is installed onto a PC. Software on the PC can then talk to the remote serial device over the network. Whilst theoretically the PLC and the PC can be any distance apart, in practice the distance may introduce some latency into the system. That may be a problem if timings in the communication between the software and PLC are important
- Two Netport mode: the second mode uses two Netports. One Netport is connected to the PLC and it then talks to the second Netport over the network. The second Netport can then be plugged into another device or PC using a serial cable.
Yes this should be possible, but you may need to use 2 Netport adaptors instead of one. The use of a single Netport requires the installation of a software based virtual serial port. The driver software supplied with the Netport that implements the virtual serial port will only work on Microsoft Windows. We would need to know a little more about what you are wanting to achieve before we can give you a definitive answer, please get in touch.
Test-Um
Yes. Whilst the Test-Um Validator and Test-Um Validator-NT are for testing copper cabling only, JDSU (the company that took over Test-Um) have now released two new products based upon the Validator technology. The JDSU ValidatorPRO and JDSU ValidatorPRO-NT both have the ability to test fibre as well as copper cabling.
Yes, the KP105 will work with all copper cable including data cable up to CAT6, coax, lighting and speaker cable. Though the KP105 won't work too well if the cable is live as the electrical signal caused by the power will effectively drown out the tone signal created by the tone generator.
Yes. Though there are other cable tracing options which may be faster and more convenient.
Yes. We are happy to help. Do you know where and when you bought the unit? The Test-Um Validator is supplied with a one year warranty so your unit may well still under warranty.If the Validator is out of warranty, we can arrange for a repair.
